【Ten Years of Great Progress in Chemical Technology】133–2023: The World’s First Full-Process System for Storing and Refilling Organic Liquids as Hydrogen Storage Medium at Ambient Temperature and Pressure

Thread Content

Ten years of rapid development in chemical technology – praise for China’s prosperity and strength. This is just a starting point; more participation from everyone will make things even more lively. HaiChuan becomes even better with your involvement; we welcome everyone to take an active part in the forum discussions. Be careful with fire risks as the heat increases in July. ********************************************* On July 6, 2023, the world’s first integrated demonstration project for storing and refilling organic liquids as hydrogen at normal temperature and pressure, developed jointly by Jian** Company and HuiYang Company, successfully completed its entire operational process at the Shanghai Carbon Valley Green Bay Industrial Park (formerly the Shanghai Jinshan Second Industrial Zone). All performance indicators met the expectations set for commercialization. This is the third commissioning test for this project. The project first produces non-toxic and odorless \"hydrogen oil\" in Fangshan, Beijing, by using a catalyst to trigger a chemical reaction between hydrogen and organic liquids. This \"hydrogen oil\" is then transported by road to the demonstration site of the Carbon Valley Green Bay Industrial Park in Shanghai, under normal temperature and pressure conditions. On-site, a dehydrogenation unit is used to treat the \"hydrogen-oil\" mixture in order to produce hydrogen that meets the standards set out in the document \"Fuel Hydrogen for Proton Exchange Membrane Fuel Cell Vehicles\", jointly issued by the State Administration for Market Regulation and the Standardization Administration of China. The resulting hydrogen is then fed into the hydrogen fuel cell vehicles, thus enabling a complete integration of the entire system throughout the whole process. This testing drive has once again confirmed that the entire system operates properly, with all performance indicators meeting the **relevant design standards. This demonstrates that the technical feasibility and economic viability of storing hydrogen in organic liquids have been validated on an engineering scale; it is now ready for large-scale commercial use. This approach enables hydrogen to be transported as easily as water, and stored as safely as water, thereby ensuring safe, cost-effective, and efficient storage and transportation of hydrogen and facilitating its widespread adoption.
